1. The responsiveness of dystrophic avian muscle to acetylcholine may be altered due to reported elevated acetylcholinesterase activity. 2. To test this hypothesis, the responsiveness of normal and dystrophic muscle in vivo to intra-arterial injection of acetylcholine, carbamylcholine and d-tubocurarine was compared. 3. Results showed that dystrophic muscle was less responsive to acetylcholine, more responsive d-tubocurarine and equally responsive to carbamylcholine when compared to normal suggesting enhanced acetylcholine hydrolysis occurs in vivo in dystrophic avian muscle.

D009119	Muscle Contraction	A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
